In material science, diffusion can take place in solid, liquid, and gases. In solids, atomic diffusion can take place with the help of thermally activated and randomly vibrating atoms. The atomic diffusion in solids is complex and very slow in comparison to atomic diffusion in liquids and gases because the interatomic distance between the atoms is smaller in solids as compared to liquids and gases.

Carbon is allowed to diffuse through a steel plate 10mm thick. The concentrations of carbon at the two faces are 0.85???3 and 0.40???3 which are maintained constant. If the preexponential and activation energy are 5.0 × 10 ―7 ?2??? and 77,000 ????, compute the temperature at which the diffusion flux is 6.3 × 10 ―10 ???2 ∙ ???
